Design of low insertion loss, single-mode polymeric waveguides |
| abstract |
The invention provides organic optical waveguide devices which are lithographically formed and employ polymeric materials having low propagation loss. An optical waveguide has a substrate; a polymeric buffer layer on a surface of the substrate; a thin, polymeric undercladding layer on a surface of the buffer layer; a pattern of a light-transmissive, polymeric core on the surface of the undercladding layer; and a polymeric overcladding layer on a top surface of the core and on sidewalls of the core and on a portion of the undercladding layer; the undercladding layer having a thickness of from about 10 percent to about 50 percent a thickness of the core. The core has an index of refraction n c which is greater than an index of refraction of the overcladding layer n o and also greater than an index of refraction of the undercladding layer nu; wherein Δn=n c −n o , and wherein the difference between n c and the index of refraction of the buffer n b is at least about 1.5 times Δn. |
